From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Increase the `maxItems` value for the `interrupts` and `interrupt-names`
properties to 11 to support additional per-channel Tx/Rx completion
interrupts on the Renesas RZ/V2H(P) SoC, which features the
`snps,dwmac-5.20` IP.

Refactor the `interrupt-names` property by replacing repeated `enum`
entries with a `oneOf` list. Add support for per-channel receive and
transmit completion interrupts using regex patterns.

Note, for adding constraints to vendor bindings patch [0] has been sent
out seprately.

v2->v3
- Dropped adding `additionalItems`
- Moved interrupts description into interrupt-names
- Replaced enum with a oneOf and added Rx/Tx regex patterns

v1->v2
- No change
